Connected to the base 10 oppositerated. It is not desired, therefore, to limit each row of pins 29 is aguide plate 30 havthe size of the table or other parts. ing perforationscorresponding to the pins Rising from the base 10 at the ends are 29 andthrough which the pins move when standards 11 in which a main drivingshaftV the rod 25 is operated. The plate 30 thus 110 serves the two foldpurpose of a guide for the pins and likewise as a stop-plate to preventthe paper or other article which is being perforated from being movedupwardly at the return stroke of the pins, as hereafter more fullyexplained.

Means are provided for actuating the rods 25, and an improved means foraccomplishing this result is shown, and consists of a cam-wheel 31mounted for rotation with the shaft 12 and provided with a cam-groove 32in which a laterally extendingoifset 33 of the rod 25 operates. Theguide 24 is provided with a longitudinal slot 34 through which theoffset 33 extends and in which it moves vertically under the influenceof the cam. By this simple arrangement it will be obvious that when theshaft 12 is rotated the cam 31 will, through the coaction of the offset33 and the cam-grooves 32 impart a vibratory movement to the rods andcause the pins 29 to pass downwardly through the plate 30 and into theperforations of the platen plate 15, and punching aperturescorresponding to the pins in any paper or other article which may beinserted between the plate 30 and the platen member 15. At the returnstroke of the rods 25 the plate 30 will serve as a stop to prevent thepaper or other article from being lifted from the table, as will beobvious, or to strip the paper from the pins.

Connected to the table 10 near one end is a gage-member 35 provided withan adjusting screw 36, while a similar gage 37 is located upon the tablenear the opposite end, and rendered adjustable by a clamp screw 38. Thegage 35 extends transversely of the base 10, while the gage 37 extendslongitudinally of the table. The gage plates thus serve as means forguiding and supporting the paper which is to be perforated, and may bereadily adjusted to correspond to the size of the paper. As beforestated, any required, number of the perforating devices may be employed,but generally three will be used, as shown. The cams 31 are eachprovided with a set-screw 39 so that the cams may be adjustedlongitudinally of the shaft and thus coact with the stop collars 26 andtheir set-screws 27 to adjust the guides 24 longitudinally of the shaftwhen required. By this means all the different parts may be readilyadjusted to cause them to operate in perfect unison.

'Ihe improved device may be constructed of any suitable material and ofany suitable size to adapt it to the work required and may be adaptedfor use in banks, commercial houses, printing oflices, or otherlocalities, but is designed more particularly in the use of printinghouses for the purpose of perforating sheets which are afterward boundin books such as checks, drafts, blank receipts, or orders and the like,and is capable of general application as an efficient perforatingmachine.

Having thus described the invention what is claimed as new is 1. In adevice of the class described, a table, a plate having a plurality ofapertures and supported upon said table, a shaft, a tubular guidedepending from said shaft, a rod slidable in said guide, a plurality ofpins carried by said rod and corresponding in number to and adapted toenter the perforations of said plate, and means operative by said shaftfor reciprocating said rod to cause said pins to enter said apertures.

2. In a device of the class described, a table, a plate having aplurality of apertures and supported upon said table, means foradjusting said plate, a shaft, a tubular guide depending from saidshaft, means for adjusting said guide upon said shaft, a rod slidable insaid guide, a plurality of pins carried by said rod and correspondingin` number to and adapted to enter the perforations of said plate, andmeans operative by said shaft for reciprocating said rod to cause saidpins to enter said apertures.

3. In a device of the class described, a table, a plate having aplurality of apertures and supported upon said table, a guide supportedupon said table and provided with apertures corresponding to theapertures of the plate, a shaft, a tubular guide depending from theshaft, a rod slidable in said guide, a plurality of pins carried by saidrod and corresponding in number to and operating through the aperturesof the guide and likewise corresponding to and adaptedv to enter theperforationsof said plate, and means operative by said shaft andreciprocating said rod to cause the pins to enter the apertures of saidplate.

4. In a device of the class described, a table, a plate having aplurality of apertures and supported upon said table, a shaft, a tubularguide depending from said shaft and provided with a longitudinal guideslot, a rod slidablein said guide and provided with an offset extendingthrough said guide slot, a plurality of pins carried by said rod andcorresponding in number to and adapted to enter the perforations of saidplate, and a cam device connected to said shaft and engaging said offsetand operating to reciprocate said rod to cause said pins to enter saidapertures.

5. In a device of the class described, a table, a member having a socketcavity and carried by said table, a plate slidable in said socket andprovided with a plurality of apertures spaced apart, means for adjustingsaid perforated plate in said socket, a rod having a pluralityof pinscorresponding in number to and adapted to enter the perforations of saidplate, and means for reciproeating said rod and the pins carriedthereby.

6. In a device of the class described, a table, a member having a socketcavity and carried by said table, a plate slidable in said socket andprovided With a plurality of apertures spaced apart, means for adjustingsaid perforated plate in said socket, a guide supported upon said tableand provided with perforations corresponding to the perforations of theplate, means for adjusting the guide, a rod having a plurality of pinscorresponding in number to the apertures of the guide and of the plateand adapted to enter the perforations of said plate, and means forreciprocating said rod and the pins carried thereby.
